lNERTIA-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 744,198, dated November17, 1903.

Application filed May 5, 1903. Serial No. 155,729. (No model.)

To all whom it may concern.-

Be it known that we, FRANK D. HOWE, residing at Bayside, county ofQueens, and LU- OIUS T. GIBBS, residing at New York, county of New York,State of New York, citizens of the United States, have invented certainnew and useful Improvements in Inertia-Govern-- ors, of which thefollowing is a specification, reference being bad to the drawings accom-IO panying and forming a part of the same.

Our invention relates to devices for automatically throttling the flowof steam, air, gas, vapor, or any other gaseous fluid whatsoever througha conduit, and while its chief utility will be found in connection withengines or motors it is obviously not limited to such application, butmay be employed with manifest advantage wherever a flow of gaseous fluidin a conduit is to be automatically. regu- 2o lated.

The essential feature of our invention consists in combining theinertiadevice and con-.

trolling-valve in one element.

It also embraces means for regulating the governor so that the same maybe adjusted to permit with great exactness any predetermined flowbetween the minimum and maximum.

It also embraces means for enabling the working parts of the governor tobe readily reached for purposes of repair, adjustment,

' cleaning, &c.

Referring now to the drawings, Figure 1 shows, partly in longitudinalsection, a convenient embodiment of our invention. Fig.

2 is a section on line 2 2, Fig. 1. Fig. 3 is a plan view of thecombined valve and centrifugal device. Fig. 4 is a sectional View of thepreferred form of our invention.

The pipe or conduit through which the gaseous fluid flows is indicatedat 1. It is preferably, though not necessarily, of modified S shape inorder to readily accommodate a shaft 2, for a purpose to be describedlater. On 5 the shaft, in an intermediate position in the pipe, is acircular disk 3, pivoted to swing freely on a diameter at right anglesto the shaft. The openingin the disk? through which the shaft passes hasits axis inclined from the perpendicular to the plane of the valve, asshown in Fig. 2 and in dotted lines in Fig. 1,,for a purpose explainedhereinafter. Slidably mounted on the shaft, but keyed thereto to rotatetherewith, is an armAt, carrying a screw device 5. The latter carriesone or more springs 6 6, seeuredat their other ends to theinertia-valve, preferably near its edge. Secured to the arm in anysuitable way is a device for adjusting the same longitudinally on thevalve-shaft.

In the pipe, at any convenient position in or near the plane of rotationof the tensionarm, is an opening closed by a removable closure 11.

same, make repairs, adjust. the tension of the springs, &c.

From the foregoing the operation of the governor will be easilyunderstood. The fluid enters the apparatus preferably from the lowerside, as indicated by the arrow. The shaft 2 is rotated by properconnection with the moving parts of the engine, to which latter thefluid is supplied. When for any reason the speed of the engine risesabove the predetermined limit, the disk 3 assumes a position morenearlycoincident with the plane of its rotation, and thus reduces the aperturethrough which the fluid passes. The supply to the engine being thusreduced, the speed immediately declines. If the speed should fall belowthe predetermined limit, the reverse op eration takes place, as will bereadily seen. At very high speeds the supply can be cut down practicallyto nothing, since the disk may be made to fit with very slightclearance, and since the inclination of the opening 3 is such that whenthe valve is approximately at right angles to the shaft the oppositeedges of the opening will be quite close to the shaft. To vary the speedof the engine, the springs 6 6 are adjusted by the screw device5. Thedegree of sensitiveness of the governor is determined by the position ofthe arm 4 on the When the plug is removed, the inner parts are readilyaccessible to clean the shaft. The former adjustment is made by slidingthe arm up to raise the limit of speed, as will be readily understood,and by lowering the arm to reduce the speed limit. second adjustment isefiected by removing the plug 11 and then altering the tension of thesprings by adjusting the screw mechanism 5.

In the form shown in Fig. 4 the speed limit and also the sensitivenessof the device can be varied without stopping the engine and cutting ofithe flow through the conduit 1. In this device the pull of the springs6, which tends to keep the valve open, is opposed by the springs 12. Thetension of the latter, and consequently the resultant force which holdsthe valve open, may be regulated by moving the collar 13 longitudinallyon the shaft 2 by means of the lever system 14. The sensitiveness of thedevice may be varied by moving the arm and collar 4 by means of asimilar lever system 15. Convenient scales and pointers 16 17, as shown,may be provided, if desired, to indicate to the operator the precisepositions of the adjusted parts.

The devices herein specifically illustrated and described are of coursetypical merely of our invention, which obviously may be embodiedinavidely-varying forms without departure from its proper scope.

What we claim is 1. The combination with a conduit, of a valve rotatingtherein, adapted to close or open the conduit by change in the speed ofits rotation.

2. The combination with a conduit, of a valve rotating therein, adaptedto close or open the conduit by change in the speed of its rotation, andmeans for fixing the limit of speed above or below which the valveoperates.

3. The combination With a conduit, of a shaft rotating therein, a diskpivoted on said shaft and rotating therewith, and spring devices tocontrol the efiect of centrifugal force on the disk, as set forth.

4. In a device of the character described, the combination with therotatable shaft and the valve pivoted thereon, of an adjustable The.

spring connected to the valve and rotating in unison with the valve andits shaft, whereby the effect of centrifugal force on the valve may becontrolled, as set forth.

5. In a device of the character described, the combination with therotatable shaft and the valve pivoted thereon, of an arm carried by androtating with the shaft, and an adjustable spring intermediate the valveand the arm, as set forth.

6. In a device of the character described, the combination with therotatable shaft and the valve pivoted thereon, of an arm adjustablymounted on the shaft and rotating therewith,and spring devicesintermediate the arm and the valve.

7. In a device of the character described, the combination with therotatable shaft and the valve pivoted thereon, of an arm adjustable in adirection parallel to the shaft, means for adjusting said arm, andspring devices intermediate the arm and the valve, as set forth.

8. In a device of the character described, the combination with aconduit, of a shaft rotating therein, a disk, pivoted on said shaft androtating therewith, spring devices arranged to hold the disk againstcentrifugal force, and spring devices to oppose the former, as setforth.

9. In a device of the character described, the combination with therotatable shaft and the valve pivoted thereon, of an arm on the shaft,spring devices intermediate the arm and the valve, an adjustable collaron the shaft, and spring devices intermediate the collar and the valve,to oppose the first-mentioned spring, as set forth.

10. In a centrifugal governor, the combination with a passage for afluid, of an automatic valve controlling said passage, adapted to beoperated by its own inertia, as set forth.
